The coolant-airsupply also powers an air-oil intensifierfor emergency stem advance and retraction.• A single control and instrumentationconsole will be provided for the necessaryelectric power, hydraulic and air controls,and for displays. Sensor displays andalignment-correction indications will alsobe shown on the console so that one operatorcan supervise the malting of a straight hole.Note that the proposed horizontal rockmeltingexcavation system which forms theglass-lined holes in place can be assembledSrom various subcomponents to produce holesof varying straightness. For example, thehole-forming assembly can:Fig. 16.Oil to CylindersOil ReturnOil to ClampsAirHydraulic and air-control circuitsfor operation of horizontal stemadvancer.• Melt an accessible, glass-lined holeunder obstructions or structures such asroads, highways, railroads, and canals wherehole straightness is not a major factor.This can be accomplished with a simple HFAconsisting of only a penetrator, glass former,and stem, as indicated in Fig. 12(a).• Melt a very straight, accessible,glass-lined hole from an established pointto intersect a target point with a maximumterminal deviation of two hole diameters orless. This will require a HFA equippedwith a deviation sensor, a surface-operatedalignment-control unit, and a sensor signalthat can be displayed on and monitored fromthe control console by the operator[Fig. 12(d)].The proposed system concepts, components,and specifications are detailed in thefollowing sections.
